COUPLING.

Specification of Letters'latent.

Patented June 8, 1909.

Application filed October 31', 1908. Serial No. 460,384.

new and useful Coupling, of which the following is a description.

The object I have in view is the production of a coupling for a bath spray or analogous structure which may be attached to faucets of various sizes and shapes, and

which will not be blown oil by the pressure of water.

A further object is to reduce the cost of the coupling, and increase its durability and make it possible to readily replace certain parts in making repairs. 7

These and further objects will appear from the following specification and accompanying drawings, considered together or separately.

In the drawings: Figure 1 is afront elevation of a faucet and a couplingembodying my invention applied thereto. Fig. 2 is a sectional view of acoupling embodying my invention. Fig.3 is a plan view of one form of ring used in connection with the coupling. Fig. 4 is a plan view of a modified form of ring and Fig. 5 is a section through the ring illustrated in Fig. l.

In all of the views like parts are designated by the same reference characters.

The coupling a comprises a rigid, hollow body'member '1, which is best made of sheet metal, and a yielding elastic top member-2,

- best made of soft rubber. To the member 1 is attached a flexible tube 3, preferably made of soft rubber. The yielding elastic top member 2 is rovided with a central opening 4 which is a apted to-go around the spout bof the spigot or cook, shown in Fig. 1. Thecentral 0 ening 4 is formed within a neck 5.

The wal s of this neck taper toward the.

lower open end, as shown in Fig. 2, and the wall of the central opening 4 is-connected with the top along curved lines, asshown.

The member 1 is provided with a'flaring.

a constricted middle portion 7,

top portion 6, and a neck 8. The lower end of the neck-has an enlargement 9 made upon curved lines, as shown. The upper edge of the flaring top portion 6 is turned over, for'min a flange 10. The yieldingelastic'top mem fir t e' 2 has a portion 0, whlch extends over flange 10 and engages withthe flaring top portion 6. below such flange. Below the flange 10 is a ring 11. Below the ring the rubber. extends downward and outward forming an annular. flange 12 The cross section of the ring is illustrated in Fig. 2 where it appears that the inner wall is inclined producmg a'tapering opening and an edge 03. The ring is placed around the top member above the annular flange 12, and lies between such flange and the flange 10. This ring will firmly hold the top member in place on'the member -1, owing tothe cooperation of the tapering inner wall of the ring, the edge d, the flaring top portion 6 of the body member and the flange, 10. The top member may be readily removed by first removing the ring 11, by slipping it over the flange 12, which flange may be readily distorted to permit this. The portion 0' of the top member is then readily removed from engagement with the flange 10. 1

According to one embodiment of my invention, the ringll carries a chain 13,which chain is adaptedto be looped around the spout I). One end of the chain is permanently attached to the ring 11 at 14, and

another portion of the chain is temporarily attached to the ring by slipping a link overa pin 15, such pin being carried by the ring 11. 'The weight of the chain will bear a ainst the spout and hold the coupling in p ace. The coupling may be adapted to fit a spoutof different size by connecting a different link of thechain 13 with the pin. I make-n0 claim to this chain broadly in this application for patent, as-the same is disclosed in a, co-pending application for patent filed by Albert N. Lattin and myself on March .13, 1907, Serial No. 362,245.

I do, however, make a claim to the combina- .tion of this chain and the ring 11. and the elastic topmember 2, for the reason that such chain exerting stress in the direction opposite to the waterpr'essure. tends to more firmly seat the rubber in'place on the hollow body member 1 Fi s. 4 and 5 illustratea ringll without the c ain. This ring may be conveniently made of a length of metal tube. The inner wall is tapered as shown so as to. produce an edge d, similar-to the edge d of the ring 11. I

Another portion of my invention relates to the attachment of the tube 3 to the hollow band may be made of a len h of metal tube and may be finished by nic el plating. The

. internal diameter of the bandis less than the external diameter of that portion of the tube 3, which lies outside of the enlargement 9. This band forms a. very eflicient means for holding the tube in place and et permits the ready removal of the tube, which is accomplished by moving the band away from the enlargement 9 in the direction toward the body member 1 and holding it in that position while the tube 3 is removed by a rectilinear movement.

In accordance with the provisions of the patent statutes, I have described the principle of m invention, together with the apparatus w ich I now consider to represent the bestembodiment. thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention can be carried out in other ways.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is

- 1. A coupling having a hollow body member, with a flaring top portion, and a flange at its edge in combinatiouwith an elastic top member, with a portion which extends over the flange, and comes into on agement flange, and a ring between the lower edge of the extending portion and the flange, the said ring hav ng a tapering bore.

3. A coupling having a hollow body member, with a fiarlng top portion, and a fian e at its ed e in combination withan elastlc top member, with a portion which extends over the flange, and comes into engagement with the flaring top portion below such flange, anda ring between the lower ed e of the extending portion and the flange, t e said ring having a tapering bore, and a chain ermanent y attached to the ring at one en and adapted to be temporarily secured at another place to the ring by means i of a pin on the latter.

This specification signed and witnessed this 29th day of October, 1908.
